Bit rate

Value indicating the amount of video data compressed in a DVD per second. The unit is Mbps (Mega bit per second). 1 Mbps indicates that the data per second is 1,000,000 bits. The higher the bit rate is, the larger the amount of data. However, this does not always mean that you can get higher quality pictures.

Chapter

Sections of a picture or a music piece on a DVD that are smaller than titles. A title is composed of several chapters. Each chapter is assigned a chapter number enabling you to locate the chapter you want.

This is the generic name of the surround

sound produced by digital signal processing

technology developed by Sony. Unlike

,Contact your nearest Sony dealer or local authorized Sony service facility and give the 5-character service number.

Example: E 61 10

This sound format for movie theaters is	Additional
more advanced than Dolby Pro Logic
Surround. In this format, the rear speakers
output stereo sound with an expanded	Information
frequency range and a subwoofer channel
for deep bass is independently provided.
This format is also called “5.1” because the
subwoofer channel is counted as 0.1 channel
(since it functions only when a deep bass
effect is needed). All six channels in this
format are recorded separately to realize
superior channel separation. Furthermore,
since all the signals are processed digitally,
less signal degradation occurs.
